Question

A cereal box measures 2 in. by 9 in. by 10 in.

1. What is the volume (in cubic inches) of the box?

2.How many square inches of cardboard make up its surface? (Disregard any hidden flaps.)

Answer 1

Hi Alyssa,

Volume of The cereal box = l * w * h

= 2*9*10= 180 cubic inches

part 2:

To calculate surface area you have to add the areas of the six faces of the box( top, bottom, front back, left and right)

Surface area= 2(2*9+9*10+10*2)

I hope you can do the Math and solve the rest of part 2
